Iscar 6402413 Boring Bar 0.2677 in Min Bore Solid Carbide

Product Description

The ISCAR 6402413 is a solid carbide boring bar designed for internal diameter turning and boring operations on CNC lathes and machining centers. With a minimum bore diameter of 0.2677 inches (6.80 mm) and a maximum bore depth of 0.827 inches, this bar handles tight-tolerance small-bore work where rigidity and cutting performance are critical. The TiCN and TiN finish coatings improve wear resistance and reduce built-up edge, extending tool life in steel and cast iron applications. Overall length is 1.4567 inches with a 7.00 mm shank diameter. The ISCAR IC228 grade is engineered for precision boring in a range of workpiece materials. Machinists and CNC operators install this tool in standard boring bar holders compatible with the 7.00 mm shank.

This boring bar is suited for small-bore internal turning on CNC lathes, Swiss-type machines, and turning centers where bore entry diameters are restricted. It is appropriate for finish and semi-finish boring passes in both production and job-shop environments. The right-hand cutting direction is standard for conventional spindle rotation. Applications include precision bore sizing in ferrous and non-ferrous workpieces requiring consistent diameter control and surface finish.

Key Features

• Solid carbide construction provides high rigidity and vibration resistance in small-bore applications
• Minimum bore diameter of 0.2677 inches (6.80 mm) enables access to tight internal diameters
• Maximum bore depth of 0.827 inches supports typical small-bore depth-to-diameter ratios
• TiCN and TiN dual finish coating improves wear resistance and reduces cutting edge buildup
• ISCAR IC228 manufacturer grade optimized for precision internal turning
• Right-hand cut orientation for standard CNC lathe spindle rotation

Compatibility

Designed as an OEM-style solid carbide boring bar compatible with boring bar holders accepting a 7.00 mm shank diameter in standard CNC turning and machining center setups.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing or setting tooling. Secure the shank fully within the tool holder to the recommended engagement depth per the holder manufacturer's guidelines to minimize overhang and chatter. Verify cutting direction and tool offset entry in the machine control before taking the first pass.
